Age per se can be a non-factor. Just follow the track record of Roger Ailes, Betty White and Nancy Pelosi. Although they are in the "aged" category that's not important. In fact, it rarely comes up in media coverage.
There are proven ways to position and package yourself as "not old." Here are 7:
When you are not at the top of your game, e.g. tired, lay low. You don't want to call attention to yourself exhibiting signs of aging. Your ailments are no one's business.
Refrain from badmouthing any generation. That comes across as being stuck. If you aren't stuck you are too busy in your own professional pursuits to over-analyze anyone else.
Don't spend excess time on Facebook. A tipoff that you are not a player is that you invest more than about 10 minutes a day updating colleagues, friends and family. One professional sidelined herself by boasting that she devotes 120 minutes daily to Facebook. We roll our eyes. Do you want her on your team?
Find ways to increase confidence. Believing in ourselves has always been a source of power. In the "Power Game" about dynamics of Washington D.C., journalist Hedrick Smith documents that. Enhanced confidence can come from coaching Generation Z on how to select a college major or chairing meetings at your support group.
Create a financial reserve. The reality is that you tend to earn less as you age. So? That's really no big deal. You need less, including the money to put the children through private school. What is the big deal is to have enough set aside for emergencies. You may need new office equipment or a roof in order to put your house on the market to sell.
Make new friends. Introducing fresh blood into our networks shakes up our thinking. We no longer will assume that everyone wants a dog or a getaway in the Hamptons. Also, extricating ourselves from old networks enables us to change our persona more easily. The familiar crowd expects us to be one way.
Be less open. The new cool is not to bore others with our overall story, the ups and downs of the day and how dysfunctional our biological family had been. Mystery always created a pull force. That's even more the situation in this era of selfies.
The date of birth on your driver's license is no longer relevant in seeking and doing work. What's critical is how you present yourself as "not old." That doesn't mean "young." It doesn't have to.
